The aim of this post is to create a movie recommendation engine through OrientDB using the same dataset used by Marko Rodriguez ( http://markorodriguez.com/2011/09/22/a-graph-based-movie-recommender-engine/ ).
First, let’s download the dataset from the grouplens website. For this specific task, i’ve downloaded the version with a million objects.
The dataset contains data about users and users occupation, movies and the ratings. With this dataset we builds a graph schema in OrientDB to create a recommendation engine.
